Explainers fail when the picture lags the words

The most common flaw in explainer video is a visual that arrives after the sentence it belongs to. Here the narration is generated before the animation, so every drawing has an exact cue in the audio and the picture lands on the word that needs it.

Good for anything with a sequence

Product onboarding, how a mechanism works, a policy change, a scientific process, a company story, a history lesson. If it can be told in order, it can be drawn in order. The samples on this site range from photosynthesis to the American Revolution to a personal-finance listicle.

Four steps, all automatic

Script: written to your length, or pasted verbatim. Storyboard: one idea per board with the exact lines spoken over it. Illustration: each board drawn as a whole picture so layout and characters stay consistent. Rendering: ink traced stroke by stroke, timed to the narration word by word.

Styles that fit the message

A clean infographic style for a product; chalkboard or classic marker for a lesson; the creative style for a story; technical line drawing for a mechanism. Twenty styles, and the same script can be rendered in several to compare.

Built for iteration

The script, the storyboard and the timing are plain text. Change one board and re-render only what changed. Director notes fix the palette, the recurring character and the production rules so the second version matches the first.

Where it is used

Marketing teams for landing-page explainers. Course creators for lesson videos without recording. Support teams for 'how do I' videos that deflect tickets. Teachers for flipped classrooms. YouTube channels for a steady weekly explainer.

Frequently asked questions

Is it really free, and is there a watermark?

Yes, and no. Every account can render one video a day, up to 10 minutes, in any style and any of 14 languages, and download it as an MP4 with no watermark and no logo. No card is needed. Minute packs, when you want more than one video a day, are one-time purchases and never expire.

How long should an explainer video be?

Sixty to ninety seconds for a product page; two to four minutes for a concept; longer only if it is broken into sections.

Can it read our existing PDF?

Document upload is on the roadmap; today you paste the text.

Can I use it for YouTube?

Yes. Videos are MP4 files at 1200×800 with narration included, ready to upload.

Will it look like every other AI video?

Each board is illustrated for your script, and director notes let you fix a palette and a character, so two videos on different topics look different.

What languages can it narrate in?

Fourteen, including English, Spanish, Hindi, Portuguese, French, Arabic, Japanese, Chinese, Bengali and Urdu.

Can I change the script after seeing the video?

Yes. Edit the text and re-render; the storyboard and timing are rebuilt.

What does it cost?

One free video per day; minute packs for more. See the pricing page.
